I Application filed January 39, 191%. serial No. 815,444.

To aZZ whom it may concern: y

. Be it known that I, HOLLAND S. Tuo rr, a citizen of the United States, residing at the city and county of Denver and State of Colorado, have invented certain new and useful Improvements in Vehicle Spring Suspensions, of which the following is a specification.

My inventionrelates to an improvement in vehicle spring suspensions, and more particularly to that form of spring suspension shown in Patents Nos. 1,029,?31 and 1,029,732 granted to me on June 18, 1912.

The object of this invention is to provide a structure in which the axle is free to more in a direction longitudinally of the frame, and the spring has the same movement simultaneously with respect to the frame.

A further object is to so arrange the parts that the spring and axle always maintain approximately the same relative longitudinal position with respect to each other.

This invention relates to certain other novel features of construction and combinations of parts which will be hereinafter fully described and pointed out in the claims.

In the accompanying drawings Figure 1 is a view in perspective show one form which the invention might take,

Fig. 2, is a view partly in section showing slightly different arrangement of the parts,

Fig. is a top plan View showing the form which might be adapted to the struc- V ture shown in Fig. 2,

Fig. sis a view in end elevation to illustrate another adaptation of load-springs,

Figs. 5, t3 and 7 show other forms which the invention might take. and 1 Figs. 8. 9 and 10 are detail views to better illustrate forms and arrangements of parts which may be used for connecting the loadsprings with the frame.

The frame A is constructed in the usual manner to comprise longitudinally-extend ing side-bars 1., 1. and suitable cross-bars 2. The axle 3 also of the usual type, as shown in Fig. l.

A modification of the semi-elliptic spring 4 is shown connected across the axle at its center by clips 7 with a cross-shaft 8 which extends parallel with the axle 8.

At each end of the shaft 8, a friction-roll 9 is mounted. These rolls, as better shown in 4 and 6, have the contact-faces thereof made Whhaped, and a suitable track 10 is secured to theside-memhers l of the frame. or is formed as an integral part thereof in which these rolls travel and are guided.

' A V-shaped reach B is secured to the axle near the ends thereof. At the angle of the reach. a sleeve 11 is provided. and :1 member 12 secured by a ball and socket joint 13 to the cross-bar 2 of the frame is adapted to fit and slide in the sleeve 11. A. full elliptic spring 14 is secured on its one side to the reach B and on its opposite side to the universal joint 13.

In the structure shown in Fig. 1. the invention is disclosed .as applied to the rear axle, and in this adaptation the sleeve 11 and the member 12, also the joint 13 are made hollow to provide a housing for the driveshaft 15. A radius-rod 16 is pivotally connected to the shaft 8 at 17 and the o )0- site end of the radius rod is pivoted at 18 to the sleeve 11. n

hen the invention is in the form tie-- scribed, the vehicle would be traveling in the direction of the arrow. Any obstruction in the road struck by the wheels mounted on the axle would cause the axle to be moved longitudinally of the frame, or, perhaps more correctly speaking, the axle would be held as the frame moves forward until the load-spring t compresses itself the long tudinal extent or the name, and by reason of the fact that the frlction rolls 9 and the tracks 10 in which they travel are made described, theshaft 8 on which the friction-rolls 9 are mounted would be held" at all times-also substantially right angles to the longitudinal extent of the'frame, and all binding would be precluded.

In the form shown in Fig. 2, the full elliptic load-springs' 19 are connected between the axle 3 and the shaft 8, and in this form the reach B is made slightly different,-it

7 being, as shown in Fig. 3, composed of two members connected near the ends' of the axle, and at their forward ends pivotally connected with arms 20 extending from a rock-shaft 20' between the side members 1 of the frame. In this form,,a straight leafv shaft 20 is twisted around its pivot, and this swinging movement is resiliently opposed by the spring 21, and, asthe obstruction is passed, the rock-shaft and consequently the axle through the connection of the reach 13 is restored to its normal position.

lVith the form shown inFigs. 2 and 3, it is preferable that two radius rods 16, 16, be provided to connect between the shaft 8 and the reach B.

In Fig. 4, the full elliptic load-spring 25 isshown in a cross-axle mounting, and in this form the parts would be as described.

Fig. 5 discloses an adaptation of the spiral load-spring to a structure very similar to that disclosed in Fig. 1. In this form the spiral springs 26 are mounted between the axle 3 and the shaft 8, and the reach structnre may be of any type so long as both the axle and the shaft may have movement longitudinally of the frame.

A. different form of endwise shoclcspring is also illustrated in Fig. 5. Here the reach is arranged similar to the disclosure in Fig.

. 1, and a spiral spring 27 is received around the member 12, and the end of the sleeve 1.1, and is connected at its one end with the reach B and at its opposite end to the movable member of the ball and socket joint 13.

lVith the arrangement illustrated in Figs. 6 and 7, the same reach structure 13 and 'endwise shock-spring 27 are adapted as the link 31 is always arrangement may be made at this cimnection between the spring and the cross-arms to accommodate the extension of the spring due .to its lierion.

As illustrated in Fig. '7, two'shafts 8" are provided to extend across the frame, and

these shafts are held and guided in thetracks 1O by the friction-rolls 9. The loadsprings 19 are connected at each end to the shafts '8.

lVith these two forms, the load-springs 19 and 19 respectively, are connected rigidly with the axle or axle-housing 3, and as the shafts 8 and 8 are connected direct with the load-springs l9 and 19 these shafts will be caused to move longitudinally of the frame in the tracks provided therefor; and it will, of course, be understood that the axle will be maintained in a position at all times at right angles to the longitudinal extent of the frame, and that this movement of the axle longitudinally of the frame will be resilientlyopposed by the spring 27, or other suitable endwise sho-clrspring.

In Fig. 8, the friction-rolls 9 are illus' trated to better show the manner in which they are mounted to move in the guides on the frame.

Fig. 9 showsa slightly different form of guiding means or slide which might be used at the ends of the shaft 8. In this form, abearinganember 28 is provided at each end of the shaft 8, and a slot 29 is provided on each of the side-members 1 of the frame, in which the slide-member 28 mounted to permit movement of the shaft longitudinally of the frame.

In F lg. 10, a modified form of mounting is disclosed. for the connection between the shaft 8 and the frame. Here a bracket 30 is carried by each of the side members 1 of the frame. A link 31 is pivoted at its one end to the bracket 30, and at the opposite end of the link the shaft 8 is pivoted. This form of connection would procure a slightly different action, but the result accomplished would be the same, and it will be noted that preferably mounted so that it is in tension. 1

Frointhe foregoing itwill be'seen that I have provided a vehicle spring suspension which comprises an axle connected by a reach with the frame to have movement lonmerges direction or the otherlongitudinally of the frame is overcome.

It is evident that more or less slight changes might be resorted to in the formand arrangement of the several parts described withont departure from the spirit and scope of my invention, and hence I do not wish to be limited to the precise construction herein set forth, but
